Homework Help: Math

Posted by Samantha on Monday, April 16, 2012 at 12:46pm.

I need help trying to write out these binomial expansions: they all need to be raised to the 8th power. Thanks

1. (x + y) 2. (w + z) 3. (x - y) 4. (2a + 3b)

- Now explain how your answer for #1 could be used as a formula to help you answer each of the other items. In each case, for #2, 3 and 4, tell what would x equal and what would y equal.

- Without writing out the whole polynomial, find the 16th term is (x + y)19. Explain how you constructed it.
